Calvin Klein gray metallic slippers/mules vintage

I'm a size 7.5 and these fit me a bit snug when I walk in them. The heels of my feet touch the end of the slippers, so when I walk them it kind of hurts so I say it fits a size 7 best! A sample shoe so it is one of a kind! Very comfy. Just bummed that they fit me small now! Few scuffs on the heel and one small stain on the left shoe (see 2nd to last pic), but other than that the shoes have a lot of life left in them! Feel free to make a REASONABLE offer
